Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of schoolbag strap processing, and particularly relates to a trimming device for processing schoolbag straps. Background Art
[0002] When processing schoolbag straps, trimming is required. Generally, a trimming device is used to directly cut the straps. However, during the cutting process, burrs are easily generated on the side of the straps, which affects the use. Moreover, when cutting, the straps lack stability and are easily driven to move due to the cutting of the tool, resulting in cutting errors.
[0003] The Chinese invention patent with the publication number CN212895614U discloses a trimming device for processing schoolbag straps. Its beneficial effect is that during the cutting process driven by a motor, the electric heating knife has a heating function, so that while cutting off the strap, the burrs can be bonded and cooled and solidified by high temperature, resulting in high neatness. While improving the aesthetics, the situation of further burr damage is avoided.
[0004] However, when this scheme is actually used, there is a lack of a structure for pressing and limiting the schoolbag straps. During the trimming process of the schoolbag straps, they are prone to deflection, resulting in cutting errors and affecting the trimming quality of the schoolbag straps. Summary of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention. Embodiment
[0022] Please refer to Figure 1-4 , the present invention provides the following technical solutions: A trimming device for processing schoolbag shoulder straps, including a U-shaped bracket 1, a bent bottom plate 2 is welded to the inner bottom of the U-shaped bracket 1. The bent bottom plate 2 is in the shape of "乁". A limit baffle 3 is welded to one side of the inner bottom of the U-shaped bracket 1 near the bent bottom plate 2. The limit baffle 3 is perpendicular to the horizontal part of the bent bottom plate 2. The limit baffle 3 is located above the inclined part of the bent bottom plate 2, which can limit the moving distance of the placed schoolbag shoulder strap. One end of the top of the U-shaped bracket 1 is fixedly installed through and penetrated with a first electric push rod 4. The output end of the first electric push rod 4 is installed with a U-shaped clamping plate 5. A first clamping tube is welded to the middle of the top of the U-shaped clamping plate 5. The output rod of the first electric push rod 4 is fixedly installed inside the first clamping tube, which is convenient for the fixed installation and use of the U-shaped clamping plate 5. An electric heating cutter 6 is installed on the inner bottom of the U-shaped clamping plate 5. The electric heating cutter 6 is located above the bent part of the bent bottom plate 2;
[0023] On one side of the top inner wall of the U-shaped clamping plate 5, an L-shaped fixed plate 7 is welded. In the middle of the bottom end of the L-shaped fixed plate 7, a second electric push rod 8 is fixedly installed through. The output end of the second electric push rod 8 is equipped with a limiting pressing plate 9. In the middle of the top end of the limiting pressing plate 9, a second clamping tube is welded. The output rod of the second electric push rod 8 is located inside the second clamping tube, which is convenient for the fixed installation and use of the limiting pressing plate 9. On one side of the top of the bending bottom plate 2, a positioning card slot 10 is opened. Near the positioning card slot 10 on the top of the bending bottom plate 2, a number of partition plates 11 are installed. On one side of the bottom end of the partition plate 11, a positioning convex block 12 is provided. The longitudinal section size of the positioning card slot 10 is the same as the longitudinal section size of the positioning convex block 12. The positioning convex block 12 is located inside the positioning card slot 10, which can position and limit the installation of the partition plate 11. In the middle of the bottom end of the partition plate 11, a limiting block 13 is provided. In the middle of one end of the limiting block 13, a limiting screw hole 14 is opened. Inside the limiting screw hole 14, a limiting screw 15 is installed, which can squeeze and limit the partition plate 11, facilitating the installation and use of the partition plate 11. On the top of one side of the U-shaped bracket 1, a controller 16 is installed. The input ends of the first electric push rod 4, the electric heating cutter 6, and the second electric push rod 8 are all electrically connected to the output end of the controller 16. The input end of the controller 16 is electrically connected to the output end of an external power supply.
[0024] The working principle and usage process of the present utility model: The user installs the partition plate 11 on the bending bottom plate 2 and adjusts the distance between two adjacent partition plates 11 so that the distance between two adjacent partition plates 11 is the same as the width of the schoolbag shoulder strap. Then the user starts the electric heating cutter 6 to increase the temperature of the electric heating cutter 6. Then the user inserts the schoolbag shoulder strap into the U-shaped bracket 1 between two adjacent partition plates 11. When one end of the schoolbag shoulder strap touches the limiting baffle 3, the user starts the second electric push rod 8. The second electric push rod 8 works to push the limiting pressing plate 9 downward. When the limiting pressing plate 9 touches the schoolbag shoulder strap, the user starts the first electric push rod 4. The first electric push rod 4 works to push the U-shaped clamping plate 5 downward, so that the electric heating cutter 6 touches the schoolbag shoulder strap to trim the edge of the schoolbag shoulder strap. The cut-off scraps of the schoolbag shoulder strap slide out from the inclined part of the bending bottom plate 2;
[0025] After trimming the edge of the schoolbag shoulder strap, the user restarts the first electric push rod 4 and the second electric push rod 8 to make the electric heating cutter 6 and the limiting pressing plate 9 return to the initial height. Then the user takes out the trimmed schoolbag shoulder strap.
[0026] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
